It's easy for first-round picks to become big names in the NFL, but the road isn't always that simple. Athletes like Kurt Warner, Rod Smith and Wayne Chrebet had to take a much more difficult path to the NFL, but once they got there people never forgot their names. Here's a look at the best players who weren't called on Draft Day, but ultimately became gridiron legends.

INVISIBLE STARS: A look at the best NFL players that went undrafted

Adam Vinatieri

Adam Vinatieri could go down as the greatest kicker of all time and no team chose to take him on draft day in 1995. After attending college at South Dakota State, Vinatieri ended up playing for the Amsterdam Admirals of the World League of American Football before the Patriots signed him in 1996. Vinatieri would go on to reward the franchise for taking a chance on him. He's known as one of the most clutch players ever with his 10 career game-winning kicks in overtime and the three Super Bowl-winning kicks in his career, which helped make the Patriots dynasty in the early to mid-2000s. Vinatieri is a four-time Super Bowl champion, has made 530 field goals in his career with a percentage of 84.3 percent and is the only player to ever score 1,000 points with two teams.
